When you write in Java "new Credentials()" it will be translated to JavaScript "new $wnd.Object". So JsInterop explicitly uses the top window referenced through GWT's special $wnd variable. If you now inject your HelloJS library into the GWT iframe using ScriptInjector then "new $wnd.Object instanceof Object" returns false as it checks the top window Object against the iframe Object.
So use ScriptInjector.fromString/Url().setWindow(ScriptInjector.TOP_WINDOW) for your Hello JS lib. Then it should work. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
